BUTTON.

SPECIFICATION forming part of Letters Patent No. 422,890, dated mirth 4, 1890.

Application filed April 10, 1889. Serial No. 306,722. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES IL PEOK', a citizen of the United States, residing at Provi= dence, in the State of Rhode Island, have invented a new and useful Improvement in Buttons, of which the following is a specification.

My invention relates to that class of but tons in which the shoe is formed by two projecting arms, one of which is attached to a fixed post and the other to a hollow post which is made to revolve on the fixed post; and my invention consists in the improved construction of the locking parts of the button, as hereinafter fully set forth.

Figure 1 represents a side elevation of the button with the arms of the shoe in the locked positionfor holding in the button-hole. Fig. 2 represents the same when the arms of the shoe are placed in position for insertion or removal from the button-hole, Fig. 3 is a view of the under side of the button with the arms of the shoe in the position shown in Fig. 1. Fig. 4 represents a section taken in the line 1 y of Fig 3a 7 Fig. 5 represents a section taken in the line a w of Fig. 3, V Fig. 6 represents an elevation of the hollow post with a portion broken away'to show the locking-pin. Fig. 7 represents aplan view of the perforated spring-plate and the fixed ar1n of the shoe.

In the accompanying drawings, A is the head of the button.

I) is the spring-plate, which is held at a slight distance from the front plate cby means of the wire ring (Z. To the central portion of the spring-plate is riveted the post 6, from the outer end of which projects the arm f of the shoe. The hollow post g, which revolves upon the post 6, is provided at its outer end with the arm h of the shoe and at its inner end with the concave disk 1', and also with the side wings j j, which serve to prevent the hollow post 9 from turning in the buttonhole. Upon the inner side of the disk. 6 are placed the pins 70 70, which serve to enter the holes Z Z in. the spring-plate b, when the arms f and h are in the positions shown in Figs. 1 and 2. The holes Z Z are so arranged relatively to the projecting end of the pins 76 is that when the button isin thebutton-hole by turning the head of the button the pins k k can be carried into and out of the holes Z Z.

Over the edge of the disk 11 is placed the annular plate m, which at its outer edge is held against the springplate b by turning over the edge of the rim n of the front plate c, the said annular plate serving to cover the joint between the disk 2' and the spring-plate.

When the movable shoe-arm h is turned to the same side with the fixed shoe-arm f, as shown in Fig. 2, the said arms can be readily inserted into the button-hole and then carried forward, so that the sides of the buttonhole will be made to embrace the wings j j of the hollow post 9. Then by turning the head A of the button the holes Z Z will be carried off of the ends of the pins 7c is, and at the completion of one-half of a revolution of the head the holes will again engage with the V said pins and the arm it will have been. car; ried to an opposite position, as shown in Figs. 1 and 3, thus serving to lock: the button to the button-hole, and a reverse movement of the head of the button will carry the arm h 7 5 back to the position shown in Fig. 2, and

then the button can be easily removed. M

The pins Z0 are made larger than the holes Z, so that only the extreme point of the pin will enter thesame, and .the consequent 8o I), and the shoe-arm f, projecting from the 0 post e, of the hollow post 9, provided at one end with the shoe-arm h and at the other with the disk 6, with the pins k, which are adapted for engagement with the holes Z of the spring and with the wings j, and the annular plate m, substantially as described.
